The problem with the OPC Item Browser

Recommended Posts

I'm using Lon OPC server to communicate with the controller.

Partly, that I am interested in, is the format SNVT_Switch and a structure consisting of two bytes.

The variable is the input.

The first byte-Value (analog), the second byte-State (control ON, OFF).

Click on the Item Proprties button "Use as Item" is not active.


Why not activated the button "Use as Item"?

How to access the bytes Value and State?

How to access the Item Quality, and to determine the accuracy of the data with the OPC Serer?

Thank you for your reply.
